RING-SPINNING FRAME.

SPECIFICATION forming part Of Letters Patent NO. 327,862, dated October 6, 1885.

Application filed April 2, 1885. Serial No. 160,990. (No model.)

To all whom it may concern Be it known that I, CHARLES H. CHAPMAN, a citizen of the United States, residing at Groton, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Ring-Spinning Frames; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings.

This invention relates to the form of spinning-machines and spindles used therefor as shown and described in my application No. 151,079, filed December 25, 1884, in which a threadguard is applied to the tip of the spindle, and the thread is extended in a direct line from the spindle-tip to the front rolls; and my present invention consists in an improved form of such thread-guard, and also in the manner of attaching the same to the frame,and in the manner of applying it to the spindle-tip.

Referring to the accompanying drawings, Figure l is a side elevation of the spindle and its bobbin with the supporting-board, threadboard, thread-guard,and ring-rail in section, and showing the relative position of the spindle-tip, thread, thread-guard, and front rolls; Fig. 2, a top View of the thread-guard, its supporting-board, and the spindle-tip; Fig. 3, a plan or top view of the thread-guard detached.

The thread-guard A is formed from sheet metal of any desired thickness, and is provided with the open slot (2, the inclined side I), and the projecting point a.

The hinged support B is preferably made from wood formed and applied to the frame in the same manner as with the present threadboard. Its front is sawed or split horizontally, as shown in Fig. 1, to receive the guard A, such guard being adjustably held therein by means of the screw 6.

The spindle-tip c is centrally drilled and spirally slotted on opposite sides, as shown, and the guard A is applied wholly above the tip, instead of surrounding it, as in my said application.

In Fig. 2 it will be seen that the projecting point a extends forward over the spindle-tip a little to one side of its center, and also that the inclined side b is so far back of the hollow center of the spindle-tip that while the guard will deliver the thread into such hollow center it does not prevent the thread from extending in a direct line from such center back to the front rolls, thus interposing nothing to arrest 5 5 the full and easy flow of the twist back to the front rolls.

In operation the thread 25 passes from the front rolls downward in a direct line over the threads-guard A and is delivered into the hollow center of the spindle-tip c, and, passing downward within such hollow tip, emerges from one of the spiral slots and passes directly to the traveler. The thread is thus twisted from the spindle-tip to the front rolls in the and the thread drops into the angle on the guard formed by the projecting point I), allowing the spind1e-tip to run ahead for the moment, or until the curved edge of the succeeding slot,passing under and behind the thread,

lifts it up and rolls it,with the aid of the trav- 8o eler, into such succeeding slot and into the hollow center, as at first, this operation being repeated at regular intervals in harmony with the falling back of the traveler to wind.

The'purpose or function of the projecting point a is to prevent the thread from swelling too far away from the spindle-tip when the thread is drawn out of the spiral slot, as described, as it would not return in season to be drawn into the succeeding slot, and would be wound around the spindle-tip were it allowed to swell too far away.

The inclined side b serves to keep the thread up when drawn out of the slot, as described,

and supports it in a position where the curved 5 side or lip of the succeeding slot can easily pass behind and under the thread and assist the traveler in returning the thread into the hollow center of the spindle-tip.

By placing the thread-guard wholly above ICO The position of the thread in the hol- 7o the spindle-tip the parts are never in contact ing-its tip centrally drilled and spirally slotand no wear takes place. It also enables me ted, combined with the thread-guard A, havto adjust the thread-guard laterally, in relaing the projecting point a and inclinedsidc b, I 5 tion to the spindle-tip, to better advantage I as shown and described.
